batch arrival queueing systemqueue lengthbusy periodsteady-state distributioncanonical factorizationA GI/G/1-type batch arrival system is considered. Explicit formulae for the distribution of queue length both at the fixed time t and as t are obtained. The study is based on the generalization of ...
and one of them is the Kingman formula. In this post I would like to introduce you to this equation and describe the fundamental understanding of it. Luckily, you don’t really need the formula for your daily dose of lean.
Various heuristics in the form of dispatching rules were applied to determine the impact of variability in the mean ratio of flow time to process time, mean queueing time, mean lateness and percentage of tardy jobs. Later on, Tunali and Orhun (1990) develop a knowledge-based system for ...
In this section, we provide formulae for the queue length process {Q(t),t≥0} with initial distribution given by P{Q(0)=n}=pn(0), where pn(0) are the periodic asymptotic probabilities for the beginning of the period. We define the functions: qn(m)(t)=∑j=n∞qn(m-1)(t) for...
In this section, we propose a generic method to analyze various discrete-time queueing systems, such as the bulk-service queue and the FCTL queue; see Sects.3and4. For these systems, the pgf of the queue length is a rational function with unknown probabilities in the numerator. The classic...

in equilibrium, with probability tending to 1 as, the proportion of queues with length equal tois at least, and there are no longer queues. We further show that the process is rapidly mixing when started in a good state, and give bounds on the speed of mixing for more general initial con...
For this purpose, we consider discrete- time nite-bu er queueing models. In particular, we study an approximate formula of the cell loss probability which is computed from the (asymptotic) tail distribution of the queue length in the corresponding in nite-bu er queue. We then apply the ...
